IBENDING-MACHINE,

Application filed November 25, 1918. Serial No. 264,090.

To all whom it may concern Be it known that I, ALFRED 1W1. MnYnRs, a citizen of the United States, residin at Merriam, in the county of Johnson and btate of Kansas, have invented certain new and useful Improvements in Bending-Machines; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a machine for binding bars, commercial shapes and the li e.

The machine is particularly adapted for use in bending angle bars to marine shapes as, for example, to conform to the desired shape for the ribs of ships, the bilge braces, shapes to be used on rudders or indeed, any curved form.

l designates a frame which ma be appropriately constructed and bracec to support the mechanism and the platform 2. Suitably supported on the base 1' is a driving member which may consist of a motor 3, on which is a pinion 4 in mesh with a gear 5 which drives the counter-shaft 6, mounted in bearings 7, 8 and 9 on plate 10. 11 and 12 are beveled pinions loose on the shaft 6 but adapted to be clutched thereto by the independently operating clutches 13 and 1 1. These pinions are constantly in mesh with the beveled gear 15 on the vertical shaft 16 and on which is a pinion 17 transmitting power to the vertical bending rollers, as will be presently explained.

The clutch 13 splined on the shaft 6 is adapted to be moved into and out of clutching engagement with the pinion 11 through the medium of the link lever 18, actuated by rod 19 on the crank 20 of the rock shaft 21 (see Figs. III and IX). The rock shaft 21 is provided with an upstanding arm 22 having a selective slot 23 adapted to receive the pivoted lever 24 loose on the rock shaft 21 and adapted to engage the selective slot 25 on the rip-standing arm 26 of the rock shaft 27 sleeved on 21. Rock shaft 27 has :1 depending crank 28 connected to an actuat ing rod 29 engaging the pivoted lever 30 which operates the clutch 14 for pinion 12.

" Therefore, if power is supplied through the motor 3, the pinion 4.- and gear 5, the counter-shaft 6 will be rotated idly unless the lever 24 is actuated to throw one of the clutches 13 or 14 into engagement with one of the gears 11 or 12 so that power will be communicated to the beveled gear 15. 'It is understood thatthe direction of rotation of the beveled gear 15 will be determined by the particular pinion thrown into mesh therewith: when the gear 15 is rotated, power will be communicated through its shaft 16 to the pinion 17 and as pinion 17 is in mesh with the spur gear 31 fixed on shaft 32, said shaft will be rotated. The shaft 32 is in fixed bearings 33and 34 and said shaft carries pinions 35 and 36. The pinion 35 meshes with a gear 37 on shaft 38 which carries the bending roller 39 consisting of a plurality of rings and which extends above the platform 2. The pinion 36 meshes with an intermediate gear 40 which in turn, drives the gear 41. The

Cal

ing with the beveled gee r 68 A,

thereto by the clutches 73 and 7a worms will be driven in opposite r bearing for the pinion 4C0 consists of a pivot or trunnion 4-2 which connects the links 43 and M on shafts of the gears 56 and i respectively, (see Fins. ll and IV). The gear ll is fixed on shaft l5 which carries the bending roller 46 adjace" t to the roller 39. 527 is a vertical shaft in fixed bearing; in the frame which carries a gear d8 meshing with the pinion 4& on shaft 32 and retated in the same direction as the gear 37 so that the roller will rotate in the same direction as the roller 39.

Thus, it will be seen that when the bar or angle, the case may be, is ted between the roller 4-6 and the re srs 39 an or the device being bent will partake "the desired curvature depending on the pressure exerted by the roller The sh on which the roller 46 mounted is laterail ble toward and away then the roll r I 50 so that the degree of curvature on t 3; bar may be determined, By rerc" Figs. VI, VH, and VH1 it will be ob that the shaft 45 is mounted in sliding ings' 51 and 52 spaced apart and mounted on the guides 53 and 5a respectively, (see Figs.

VI and VIII) in line with but 'lX'Jt with re spect thereto, and spaced from the sliding bearings 51 and 52 ar boxes and in which are the threaded ends 57 and 58 of the screws 59 and 60. These screws are fixed to the sliding bearings 51 and 52 and have threaded engagement with the worm gears 61, which are adapted to rotate the boxes and 56 but which have no end\ movement. These gears 6i are driven by the worms 62 so that when rotated a longitudinal increment parted to the screws to shin" t t laterally. gears 63 and 64 through tire intermediate pinion (35 which motion from the shalt (56 to which receries its hired:

From the foregoing it will be apparent that these rollers may be conveniently adjusted vertically to accommodate them to various conditions. It will also be apparent that the work may be conveniently ted between the vertical rollers and any desired curvature within certain hints may be imparted to the bar, angle, channel, I-beam, or other commercial shapes and that any desired pressure may be exerted by the roller 46.

What I claim and desire to secure by Letters-Patent is:

1. A bending machine comprising a base, vertically disposed bending rollers carried by the base, a supporting; roller, amounting tor the supporting roller comprising a block a depending shank on said block, angular in cross-section and having atransverse rectangular opening', guiding means for the said shank, a rock shaft, a cam on the rock shaft and within the rectangular opening, and means for efiecting rotative adjustment of said rock shaft.
